CDM3S molded case circuit breaker
Navigator series new CDM3S molded case circuit breaker. In low-voltage distribution lines, a mechanical switch that can connect, carry and break current under normal circuit conditions, and can also connect, carry and break current for a certain period of time under specified abnormal circuits, is used in distribution lines. Provide protection for lines and equipment in the event of overload, short circuit, and undervoltage (accessory function). It is widely used in low-voltage power places such as electric power, construction, industry, OEM, etc.
CDM3S series products are a new generation of products that inherit the classic technology platform and are newly created, including CDM3S thermal magnetic molded case circuit breakers, CDM3LS residual current operated circuit breakers and CDM3G isolating switches . The new series of products cover 63 to 1600 frame in an all-round way, with stronger structural design and more varieties of accessories. The innovative thermomagnetic molded case circuit breaker communication function improves the wiring capacity and creates a more cost-effective and more reliable circuit breaker for customers. Products to meet the application needs of various customers.

(see the parameter table for the specific breaking of each frame)
● Number of poles: including 2-pole, 3-pole and 4-pole products
● Release type: single magnetic type, thermal magnetic type
● Installation method: fixed, plug-in, drawer
Normal working humidity: when the ambient air humidity is +40°C, the relative humidity of the atmosphere cannot exceed 50%; if the temperature is low, it can be used at a higher relative humidity; for example: +20°C time, up to 90%. Special measures should be taken for occasional condensation due to temperature changes; reliable contact indication with isolation function Isolation as defined in IEC standard GB/T 14048.2 The isolation position corresponds to the O (OFF)
Only the contacts are truly open , operate the handle to indicate the “OFF” position
● Rotating the handle or the electric operating mechanism will not change the contact indication system
